The partner notification service is part of a public health initiative to help protect the public and limit the spread of STIs.

When you choose to use this service to inform one or more sexual partners that you’ve been diagnosed with an STI, you are acting privately and anonymously, as well as individually and of your own volition, in a spirit of goodwill and respect, and with full knowledge of the potential consequences.

Your aim is to inform each person you contact of your diagnosis, in order to encourage them to see a doctor. Once you’ve sent a message, it cannot be changed. Please read the Legal Note before using this service.

The HPV family includes nearly 200 viruses that differ in their genetic composition. For this reason, we speak of HPV types.

About 40 HPV types can infect the genitals and the anus. Some of these viruses can also affect the mouth or throat.

HPV types 6 and 11 cause more than 90% of condylomas, also called genital warts. These types are considered low risk as they’re not typically linked to cancers.

HPV types 16 and 18 cause 77% of cervical cancers, 40% of vaginal and vulvar cancers and 90% of anal cancers. These types are considered high risk as they’re frequently linked to cancers.

What are the symptoms of the various HPVs?

Types 1 and 2 cause warts on the hands, but not on the genitals or the anus. Types 6, 11, 40, 42, 43, 44, 53, 54, 61, 72, 73 and 81cause genital warts in the shape of tiny cauliflowers. However, types 6 and 11 cause 95% of HPV-related condylomas. Types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 are 68 considered high risk for cervical cancer. Types 16 and 18 are the most dangerous, as they’re responsible for about 70% of cervical cancers, and they lead to cancer much faster than other high risk HPVs.
In one study, the American National Cancer Institute concluded that about 10% of women who were carriers of HPV type 16 or 18 developed an advanced premalignant growth on the cervix (CIN 3) within three years, versus only 4% for female carriers of any other type of HPV. In addition, 20% of carriers developed CIN 3 within ten years, versus 7% of women who carried any other type of HPV.

A global health concern

Worldwide, HPV is the most common sexually transmitted infection.

Young people are most affected, although all age groups can be at risk.

How HPV spreads

HPVs are transmitted through close contact, frequently with a person who is contagious but unaware that they carry the virus.

Vaginal and anal penetration are the most effective means of transmitting HPV.

HPV can spread through genital or anal contact between sexual partners.

The virus cannot be contracted from clothing, soap, bedding, toilet seats, and so on.

How HPV acts in the body

Once HPV is transmitted, the virus establishes a chronic infection in the cells.

A significant proportion of people infected show no symptoms.

The majority of those who contract HPV are chronically infected. Consequently, the period between infection and the appearance of symptoms can range from a few months to several decades.

Even without showing symptoms, the infected individual can transmit the virus to future children or sexual partners.

After visible symptoms have disappeared, no test is available to determine whether the virus remains in the body.

Symptoms

Most lesions are transitory, lasting several months to years.

Some occur more frequently, such as condylomas (see the “HPV and condylomas” section) and abnormal cells on the cervix (see the “HPV and the Pap test” section). Other lesions are less frequent but more serious, such as premalignant cells on the vulva, vagina or anus, as well as cancerous growths in these regions and in the mouth or throat.
